Here's a little ditty about John Mellencamp and Elaine…
The singer, 59, and his wife have decided to divorce after 20 years together, a source confirms to UsMagazine.com.
"They are both devastated and upset about it, but it was really her decision," the source tells Us.
The couple, who live together in Indiana, share two children.
"John and Elaine Mellencamp are proud of their 20 years together and are very happy with their accomplishments both as parents and as a family. They will continue to raise their two children in Indiana but have decided to call it a day as a couple," his rep told E! Online in a statement.
